The remarkable intricacy of human general intelligence has so far left psychologists being unable to agree on its common definition. The framework definition of general human intelligence, suitable for a discussion herein and as proposed by an artificial intelligence researcher David L. Poole, is that intelligence is wherein “an intelligent agent does what is appropriate for its circumstances and its goal, it is flexible to changing environments and changing goals, it learns from experience, and it makes appropriate choices given perceptual limitations and finite computation”. Learning from past experiences and adapting behavior accordingly have been vital for an organism in order to prevent its distinction or endangerment in a dynamic competing environment. The more phenotypically intelligent an organism is the faster it can learn to apply behavioral changes in order to survive and the more prone it is to produce more surviving offspring. This applies to humans as it does to all intelligent agents, or species.
